Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically a wood sanding machine. Background Technology

[0002] Wood is the lignified tissue formed by plants capable of secondary growth, such as trees and shrubs. After the primary growth of these plants ends, the vascular cambium in the rootstock becomes active, developing phloem outwards and wood inwards. Wood plays a significant supporting role in human life. Based on different properties and characteristics, people use wood for various purposes, such as furniture and housing.

[0003] Currently, sanding is an essential step in the initial processing of wood, otherwise the rough surface of the wood will affect its subsequent use. However, most wood sanding machines currently in use rely on manual labor to move and fix the wood during the sanding process in order to reduce operating costs and difficulty. Although this can achieve the processing purpose, it has significant limitations in terms of efficiency and safety. Utility Model Content

[0029] Working principle:

[0030] Example 1

[0031] The wood blank 5 is placed in the clamping space. Then, the cylinders 81 set in the front and rear ends of the second processing platform 7 are started. The output ends of the two opposing cylinders 81 drive the corresponding clamping plates 82 to automatically clamp and limit the wood blank 5. After the wood blank 5 is restricted and stabilized, the auxiliary motor set in the grinding wheel assembly 11 is started. The output end of the auxiliary motor synchronously drives the corresponding transmission shaft 111 to rotate synchronously. Then, under the synchronous operation of the other transmission shaft 111, the support of the outer support shell and the synchronous belt 112, the grinding wheel body 113 corresponding to the other transmission shaft 111 will be driven and rotate synchronously with the output end of the auxiliary motor.

[0032] Next, the first brake servo motor 101 is controlled and its output is made to move back and forth. Then, the output end of the first brake servo motor 101 drives the transmission gear 102 to move back and forth. At the same time, the transmission gear 102 reciprocates and meshes with the linear gear plate 9, so that the linear gear plate 9 drives the second processing platform 7 and the wood blank 5 inside the second processing platform 7 to move back and forth in the sanding space 6.

[0033] After the wood blank 5 reciprocates, the second brake servo motor 124 is started and outputs in the forward direction. The output end of the second brake servo motor 124 engages with the transmission nut 122 through the lead screw 121, which in turn drives the first processing platform 2 to move upward through the transmission plate 123. The constraint rod 3 constrains and guides the movement of the first processing platform 2. After the wood blank 5 contacts the grinding wheel body 113 to a specified depth, the second brake servo motor 124 is turned off, while the output of the first brake servo motor 101 and the auxiliary motor is maintained until the surface of the wood blank 5 to be processed is sanded. After completion, the second brake servo motor 124 is restarted and outputs in the reverse direction, moving the first processing platform 2 down to reset. Then, the auxiliary motor is turned off, stopping the operation of the grinding wheel body 113. Finally, the two cylinders 81 are turned off, and the processed wood blank 5 is taken out.

[0034] Example 2

[0035] For sanding the edge of the wood blank 5, the steps of Embodiment 1 above shall be followed. During the sanding process of the grinding wheel assembly 11 on the wood blank 5, the negative pressure suction port of the existing negative pressure dust collection equipment can be connected to the open end of the transition guide pipe 16. Then, the electric push rod inside the auxiliary lifting assembly 15 is activated. The output end of the electric push rod drives the inverted C-shaped baffle 14 to move down through the linkage plate. Then, the auxiliary lifting assembly 15 moves down through the inverted C-shaped groove and forms a semi-open dust collection space fitted outside the grinding wheel assembly 11 with the auxiliary baffle 13. After the auxiliary lifting assembly 15 and the auxiliary baffle 13 are stable, the negative pressure dust collection equipment is activated. The wood chips from the rotating sanding of the grinding wheel body 113 are automatically collected through the transition guide pipe 16 and the semi-open dust collection space.
